BCM's can be a little tricky in LH Cars. Options in the "donor" car need to match the car the BCM is installed in to avoid reprogramming.
Last two letters are the revision code of the base part. AE would be and earlier version of AH
Security key is tied to the PCM so no real issues there but odometer may show mileage in the BCM

If all of the features are the same will it worm despite the vin number being different?
